The Substitute(1961)

A character arrives at the beach and thanks to his air pump, creates loads of useful inflatable things to make his day enjoyable. He has a tent, a table, chair and even a barbecue. He makes his own fish, then a fishing rod then after supper - complete with wine, he creates his own lady friend. She's not so keen on him though and when she runs off with an equally blown up lifeguard to a nearby island, he must pursue and thwart their ardour. You just know what's going to happen at the end, but even if the style of animation is a bit basic, the build up to that denouement is quite entertaining. Quirky, and worth ten minutes, I'd say.
